Thank you all for your helpful replies, I know about the Census and have checked out the Valuation-Electoral Rolls, unfortunately the records for the Falkirk District stop in 1923 and don't begin again till 1949. I live close enough to Falkirk & Edinburgh to check any records available, there are none, hence my plea for help.
Perhaps a little background might interest you all.
Uncle John was a Fireman serving aboard the SS. Socony Oil Tanker engaged in the WW2 Convoys from America which saved the UK from utter starvation during the war, suffering more than 50% losses to U Boats every trip. His shipmates complained to the Captain that he was talking to himself and shouting out in his sleep, disturbing others. He was interviewed by the First Officer who gave him strong sedatives to calm his nerves, sent him aft with a note to the Cook to give him a meal and ordered bed-rest. On his way aft, John was seen to go to the side of the ship and leap overboard, he must have been sucked under and hit by the Ships Propeller, he was seen to surface behind the ship for a time. Under orders not to stop, or deviate from its course in the Convoy, the Captain could only signal "Man overboard" to following ships in the hope he would be seen, John was lost.
His ship, SS. Socony, was owned by American company, Socony Vacuum Transportation Co. which became Standard Oil. The ship SS. Socony was in collision two voyages later and sank with all hands.
SOCONY; Owned by the Socony Vacuum Transportation Co. and built in 1936 by Bremer Vulkan, Germany; 4,404 tons; 349.7x52.3x29.6; 425 n.h.p.; compound engine
While on her way with lubricating oil from Bay town to London, the British tanker Socony sank after a collision with the Tongariro on September 9th, 1941.
I would just like to know more about Uncle John before these sorry events happened, as I said I have his last known address in Grangemouth from the Merchant Navy, the house and street still exist but nobody there is old enough to remember wartime events. Having served in the Merchant Navy myself, I know what The Cruel Sea is like, but I can't begin to imagine what it was like serving in a floating bomb, setting out knowing the Wolf Packs of Submarines were waiting for you to pass at your maximum speed of 10 Knots, half that in bad weather.
